China has a serious health issue on its hands with a type of oil production known as ‘gutter oil’. This is where people will go through dumpsters, trash bins, gutters and even sewers, scooping out liquid or solid refuse that contains used oil or animal parts. They will then process this into cooking oil, which they sell at below-market rates to food vendors who use it to cook food. In turn this causes a lot of people to become extremely sick.

The below video, produced by Radio Free Asia, shows in excruciating detail how a couple of gutter oil vendors go about their work.
